[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figure 1-5The utility model provides the following technical solutions: a hinge structure for a sun visor of a commercial vehicle, comprising a hinge pin 1, a hinge box 2, a plurality of metal clips 3, a plurality of metal clips 4 and a screw 5, the hinge pin 1 is arranged in the hinge box 2 and rotates therein, a plurality of metal clips 3 are clamped on the hinge pin 1, the hinge pin 1 rotates in the metal clip 3, the metal clip 4 is opposite to the opening of the metal clip 3 and is covered and fixed inside by the hinge box 2, the opening of the metal clip 4 is larger than the metal clip 3, the opening of the metal clip 4 covers the opening of the metal clip 3, and the length of the metal clip 3 is longer than the metal clip 2 4. The hinge box 2 is fixed to the sun visor by screws 5. The unfolding, closing and hovering of the sun visor are all realized by the rotation of the hinge pin 1 in the metal clip 3. When the metal clip 3 is stretched open by the hinge pin 1, causing the opening of the metal clip 3 to become larger and contact the opening of the metal clip 2 4, the metal clip 2 4 restricts the metal clip 3 from escaping from the metal clip 2 4, so as to prevent the position change of the metal clip 3 from causing the rotation of the hinge pin 1 to drive the rotation of the sun visor to fail. The metal clip 1 3 and the metal clip 2 4 are always covered and fixed by the hinge box 2, which improves the fixing strength and improves the stability of the hinge pin 1 rotating in the metal clip 3.

[0017] Specifically, a plurality of clamping parts 11 are arranged in the middle part of the hinge pin 1, and cylinders 12 are arranged on both sides. Limiting parts 13 with a larger diameter than the cylinders 12 are arranged on the outer sides of the cylinders 12 on both sides of the hinge pin 1. The diameter of the clamping part 11 is smaller than the diameter of the cylinder 12. A protrusion 14 with the same diameter as the cylinder 12 is arranged between the clamping parts 11. The metal clip 3 is clamped on the clamping part 11. The setting of the protrusion 14 prevents the metal clips 3 on each clamping part 11 from moving left and right, and limits the plurality of metal clips 3 on the clamping part 11 respectively.

[0018] Specifically, a through hole 21 is provided on the hinge box 2, and the hinge pin 1 is located in the through hole 21. The diameter of the limiting parts 13 on both sides of the hinge pin 1 is larger than the diameter of the through hole 21. The limiting parts 13 on both sides limit the hinge pin 1 in the through hole 21, and the hinge pin 1 will not move left and right.

[0019] Specifically, the outer side surface of the clamping portion 11 includes a plane surface 111 and a cylindrical surface 112 .

[0020] Specifically, the end of the metal clip 3 away from the opening is an arc 31, and the rest of the metal clip 3 is horizontal. The size of the opening of the metal clip 3 is smaller than the size of the arc 31. When the sun visor is closed, the plane 111 of the clamping part 11 is clamped with the metal clip 3. When the sun visor is opened, the cylindrical surface 112 of the clamping part 11 is clamped with the arc 31 of the metal clip 3 to achieve hovering at a certain opening angle.

[0021] The installation and movement process of the utility model is as follows: the assembly process is: first install a plurality of metal clips 3 on the clamping part 11 of the hinge pin 1, then wrap the opening of the metal clip 2 4 around the opening of the metal clip 1 3, then cover the metal clip 1 3 and the metal clip 2 4 with the hinge box 2 and clamp the hinge box 2 itself, at this time the clamping part 11, the cylinder 12 and the protrusion 14 on the hinge pin 1 are located in the through hole 21 of the hinge box 2, and finally fixed to the sun visor by the screw 5. The movement process is: when the sun visor is closed, the plane 111 of the hinge pin 1 is clamped with the metal clip 1 3, and when the sun visor is opened, the cylindrical surface 112 of the clamping part 11 is clamped with the arc 31 of the metal clip 1 3, and hovering is achieved at a certain opening angle.

[0022] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents.
